My script isn't working properly, what were you excepting me to write?

(sorry for the title, but lol) Alright, i'm making an explorer for a script builder for training purposes. Everything's working well, BUT... I'm trying to make a search function which haves to search for objects. (duh) It does it job well, but makes like kinda "gaps" which i didn't want to appear. I can't explain it but try trying out the explorer and try to search something which appears at the top of the explorer, then something at the bottom of the explorer, you will notice that in the second search the object will need to be scrolled down to.

Very hard to explain, but..

Here's the code: (localscript) [the line i think is not working propellery is 83]

-- variables
local me = game.Players.LocalPlayer

-- Create ScreenGui
local screenGui = Instance.new("ScreenGui")
screenGui.Parent = me.PlayerGui

-- Create ScrollingFrame
local scrollingFrame = Instance.new("ScrollingFrame")
scrollingFrame.Position = UDim2.new(0.2, 0, 0.1, 0)
scrollingFrame.Size = UDim2.new(0, 200, 0, 300)
scrollingFrame.CanvasSize = UDim2.new(0, 200, 2, 0)
scrollingFrame.BackgroundColor3 = BrickColor.Blue().Color
scrollingFrame.Parent = screenGui
scrollingFrame.ScrollingEnabled = true
scrollingFrame.Active = true
scrollingFrame.Draggable = true
scrollingFrame.ScrollBarThickness = 12

-- Create SearchBar

local s = Instance.new("TextBox", scrollingFrame)
s.BackgroundColor3 = BrickColor.White().Color
s.TextColor3 = BrickColor.Black().Color
s.Size = UDim2.new(0,125, 0,50)
s.Text = "Search"
s.TextScaled = true
s.Position = UDim2.new(0,0, 0,0)
